Nira usually sleeps in a corner of the street, the grabage bags serving her as pillows. Her favorite food is spaghetti. She has a pet hedgehog named Uniguri-kun. She likes to use a metal pipe as a weapon. She desires to carry on with life unconsciously, explaining her disinterested and neutral behavior sometimes. She was given a pair of glasses by a strange cat that gives her the ability to go to other dimensions. When she gets in action, she is rude, uncaring and tries to get as much fun.
